1.The reaction: 4A(g) + B(g) ←→ 6C(g) is at equilibrium in a piston. Suddenly, the volume is decreased to ¼ of the initial volume. In which direction will the reaction shifts towards to reestablish equilibrium? (1 point ) *

No change

No change ONLY if the reaction is endothermic

None of the above

Reactants

2.For the reaction H2(g) + I2(g) ↔ 2HI(g), Kc = 50.2 at 445 oC. If [H2] = [I2] = [HI] = 1.75 × 10^(-3) M at 445 oC, which one of these statements is true? (1 point ) *

Concentration of HI will increase as the system approaches equilibrium

Concentrations of H2 and HI will fall as the system moves toward equilibrium

Concentrations of HI and I2 will increase as system approaches equilibrium

None of the above
